Description

Technical Field

[0001] The invention relates to an earphone, in particular to a bone conduction swimming earphone. Background Art

[0002] The working principle of bone conduction headphones is to convert sound into mechanical vibrations of different frequencies, and use the human skull, bony labyrinth, inner ear lymph, spiral organ, and auditory center to transmit sound waves. This method eliminates the step of sound waves transmitting in the air, and can achieve clear sound restoration in a noisy environment. At the same time, the sound waves will not affect others because they diffuse in the air; bone conduction headphones are often used in the field of swimming.

[0003] The use environment in the field of swimming includes the guidance and teaching of coaches to newcomers. Affected by factors such as the empty swimming pool environment, noisy and numerous swimmers, and water bodies, it is difficult for coaches to provide real-time guidance on the swimming posture of newcomers, which greatly increases the difficulty of the coach's teaching and also greatly affects the speed of newcomers' progress. In addition, the existing bone conduction headphones are fixed to the swimmer's head through elastic straps. Before wearing, it is necessary to pre-adjust the length of the straps according to the size of your head, and then wear them. If the tightness is not appropriate, you need to take off the headphones and the straps and adjust them again, which is cumbersome to operate; in addition, due to the influence of the materials of the swimming cap and the straps, the contact friction resistance between the two is large, which makes the position adjustment of the straps after wearing more difficult, and it is impossible to achieve smooth adjustment, which further increases the cumbersomeness and workload of the adjustment operation. Summary of the invention

When in a normal non-wearing state, the sealing component is at the first sealing level to ensure daily sealing between the upper shell and the lower shell. When in a swimming wearing state, the sealing component is triggered by the set trigger component to switch to the second sealing level to achieve further sealing between the upper shell and the lower shell, to achieve a better sealing effect, prevent water ingress, and improve the reliability of the structure.
